What would be optimal for the DVB captures is having the original raw files that were used to make the various versions. It would give the opportunity to see what was there before processing was done in the digital domain.
Another optimal solution would be to have access to the actual "professional digital tapes" that may possibly have been used in their raw format.
New sets of eyes and ears can make a world of difference especially with more experience.
Of course, 35mm film would be the best option .... but money and equipment would be the most obvious set backs.
I really want to see this set be a success .... for everyone to enjoy.
